Definitions
- the invention relates to a method for producing switch sleepers.
- Switches are track designs that enable rail vehicles without interruption to move from one track to another.
- the switches lie on special switch sleepers, which are longer than normal sleepers and today are preferably made of prestressed concrete.
- a switch with a typical length of 30 to 150 meters and a typical distance between the sleepers of 0.6 meters requires a large number of different switch sleepers, which differ in terms of their length and the mounting position of rail fasteners. The construction of a switch and the production of the required switch sleepers is thus much more complex compared to a normal rail carriageway.
- Switch sleepers were previously manufactured in the so-called long-sized fitted bed.
- Fitted bed can be 100 or 150 meters long, so this process requires a lot of space.
- As a reinforcement are usually several
- Tension rods used which are pulled through the clamping bed and tensioned.
- the clamping bars are cut apart between the molds so that individual prestressed switch sleepers are formed.
- This manufacturing process is comparatively slow and inflexible.
- the invention has for its object to provide a method for producing switch sleepers, which can be performed easier and more flexible.
- a method for producing sleepers which differ in each case with respect to their length and the mounting position of rail fasteners, provided in the circulation method, comprising the following steps: Attaching one or more Abstellbleche and / or one or more inner molds in one Sleeper shape, according to the length and the shape of the turnout threshold to be manufactured or using at least one adapted to the geometry of the turnout threshold to be manufactured threshold shape; Inserting tension rods as reinforcement; automatic simultaneous tensioning of the tensioning rods with spindle pairs, each tensioning rod being tensioned individually; Pouring concrete into the sleeper mold; Curing the switch threshold; Demoulding the turnout threshold.
- the invention is based on the finding that the production of switch sleepers is possible by the threshold shapes are adapted by Abstellbleche or inner molds (mold inlays) to the different lengths and the different mounting positions of the rail fasteners of the individual switch sleepers.
- a sleeper mold can either be made suitable for the respective turnout threshold or can be adapted to the geometry of the turnout sleeper by means of mold inlays or be adapted to different turnout sleepers by means of storage shelves.
- Shelves and / or the inner molds suitably furnished. In the first place, the shelves or the inner molds put the lateral ends of a
- Mounting position of rail fasteners can be adjusted by appropriate shelves or other inserts in the sleeper shape.
- the production takes place in direct composite, wherein after insertion and clamping of the Tension rods as reinforcement of the concrete is poured into the sleeper shape. After hardening and demoulding of the points threshold to get a prestressed points threshold, the production of which is completed by the installation of rail fasteners.
- An adaptation to different threshold lengths is carried out by used in the sleeper mold shelves and / or inner molds (mold inlays).
- the clamping rods are held individually at one end by means of an anchor and at the opposite end by means of a clamping device, wherein the armature and the clamping device on the or a shelf and / or an inner mold and / or an end face of the sleeper mold is or are.
- a threshold form in which two, three, four or more side-by-side switch sleepers are produced.
- a sleeper shape either a shim may be used that is mounted across the sleepers and thus limits the length of all sleepers in the sleeper mold; alternatively, four sleepers may be used in a sleeper mold including four sleepers so that four different sleepers are made simultaneously can be.
- four sleepers may be used in a sleeper mold including four sleepers so that four different sleepers are made simultaneously can be.
- several, for example four, different inner forms to be incorporated or inserted into a sleeper mold, or the shape can be adapted to a plurality of, for example four, different geometries.
- a switch threshold is provided with four tension rods or prestressing steels.
- the four tensioning bars or tensioning steels can be clamped automatically, the tensioning being carried out simultaneously and individually for all tensioning bars.
- the invention relates to a switch threshold, which is produced by the described method. This switch threshold differs in terms of their structure from well-known switch sleepers, which are made in a conventional manner in the long clamping bed.
- Fig. 1A shows threshold forms used in the methods of the invention until 1D;
- Figure 2A shows various views of a sleeper mold with inserted to 2C tie rods.
- FIG. 3A different views of a switch threshold according to the invention. to 3C
- Fig. 1A shows a first threshold form which can be used in the method according to the invention for the production of switch points in the circulation method.
- the sleeper mold 1 is designed as a multiple mold in which four switch sleepers can be produced simultaneously.
- the threshold form is an open-topped box and is divided by partitions 2 into four sections, in each of which a switch threshold can be made.
- Abstellbleche 3 can be used to vary the interior of the sleeper mold 1, in particular, so that the length of a switch point to be manufactured can be changed.
- the Abstellbleche 3 can be mounted in different ways in the sleeper mold 1, for example via a screw, a connector or by inserting into a threshold-side groove.
- the attachment can be done by welding or a magnetic holder or the like.
- the sleeper mold 1 corresponding fastening devices are provided, so that the storage shelves 3 are flexibly positioned and easily removed again and used at another location.
- the Abstellbleche are continuously fastened in the sleeper shape, so that any desired length of a switch threshold can be made.
- the baffles for several switch sleepers can be positioned at the same location in the sill form 1, alternatively, each of the four switch sills produced with the sill form 1 shown in Figure 1 may have a different length
- the shelves devices or inserts are mounted for rail fasteners in the form whose position varies with the length of the switch threshold. These fasteners can also be flexibly positioned at different locations of the sleeper mold 1.
- Figures 1 B, 1 C and 1 D show further forms of sleep in which three, two or only a single turnout can be made simultaneously.
- Figures 2A, 2B and 2C show a detail of a threshold shape in different views.
- Fig. 2A is a sectional side view of a sleeper mold 4.
- Fig. 2B shows the associated plan view,
- Fig. 2C shows a front view of the sleeper mold.
- tie rods 5 (prestressing steels) are used, which serve as reinforcement for the turnout sleeper. As can be seen in FIG. 2C, four tie rods 5 are used per turnout threshold. On one side of the sleeper mold 4, the tie rods 5 are held by anchor bolts 6, which are supported on the side wall 7 of the sleeper mold 4. At the opposite end of the sleeper mold 4, the tie rods 5 are fixed with clamping bolts 8, which are supported on the side wall 9 of the sleeper mold 4. Before filling concrete, the tie rods 5 are biased by a nut 10 according to the static requirements of the switch threshold. If necessary, storage shelves 4 are used in the sleeper mold 4, which however are not shown in FIGS. 2A to 2C for reasons of clarity. In addition, further inserts may be provided for the sleeper mold 4 to create a special profiling of the switch sleeper or to create mounting points of rail fasteners.
- a switch point 11 produced by this method is shown in different views in FIGS. 3A to 3C.
